ANTIFREEZING VALVE AND CLOSTFCISTERN.

SPECIFICATION forming part of Letters Patent No. 672,469, dated April 23, 1901. Application led December 27, 1898. Serial No. 700,321. (No model.)

To all whom it may concern/f Be it known that I, GEORGE W. WILKEs, a citizen of the United States, residing at Fort Worth, Texas, have invented certain new and useful Improvements in Antifreezing Valves and Closet-Oisterns, of which the following is a specification.

This invention relates to valves and to certain improvements for operating the valves when applied in connection with closet-cisterns, hydrants, sinks, and other devices; but the invention relates more particularly to antifreezing valves which can be removed and repaired without disturbing the supply and waste pipes which are attached to the outside casing; and the objects are to construct valves which will allow all the water to flow out of the pipes to a position below freezing-point after each application of water, whether the water is used in a closet-cistern or drawn out of a hydrant or other applicatern, illustrating au improved lever for operating the improved valve and the outer part of the siphon of the closet-cistern, which is fully described and illustrated in my pending application, Serial No. 689,290, filed August 23, 1898. Fig. 2 is a vertical section of the detachable valve-chamber and its casing. Fig. 3 is a sectional view illustrating` a rodcoupling. Fig. 4 illustrates a variation in means for operating the valve. Fig. 5 is a Vvariation in the arrangement of the wastevalve, the chamber being shown in a sectional view. Fig. 6 is a vertical sectional view of a valve-chamber and its casing, showing a variation in the arrangement of the waste-valve.

Similar characters of reference are used to indicate the saine parts throughout the several views.

Figure 1 is a vertical section of a closet-cis- The cistern-boX 1, the si phon, consisting 0E the cylinders 2 and 3, their mountings, and the rod 4, with its connections and mountings, are exact-ly the same as the corresponding parts in the application referred to above and will not be described in detail in this application.

I use an improved lever 5 for operating rod 4 and the outside cylinder of the siphon and which is operated by the siphon. The lever is pivotally at the top edge of the box and is connected to the top of Jthe outside cylinder of the siphon at one end, and a cord 6 is attached to the other end. I make the rod 4 in two or more parts, and I use a rod-coupling consisting of a tube 7, having an aperture in one side, and a pin b'. The two parts of the rod 4 are bent at the juncture and the ends project out in the aperture in the tube, and the pin is inserted in the tube on the opposite side of the rodfsections, so that the bent ends of the rod-sections cannot be withdrawn from the aperture until the pin is removed. Rod 4is operated by lever 5, which has a loop 9 cast integral therewith and provided with apertures, so that the rod 4 may be attached at various adjustments. The rod 4 extends down through the valve-chan1ber 10 and is bent near the end, and a valve 11 is attached thereto. The valve-chamber 10 is screwed into a casing 12. The casing has a wasteopening 13, a supply-opening 14, and offset 15, (annular in crosssection,) on which is placed a washer 16. The valve-chamber 10 has an annular shoulder 17, which comes to rest on the washer 16 when the chamber is screwed down in the casing l2. This chamber has a central channel in which the rod 4 operates and through which water passes. It

has also a channel for a valve 18, which is the waste-valve. Valve 18 is provided with a seat 19, cut in chamber 10, and an aperture 20, which aperture leads to the channel 21. This channel is formed between the interior wall of the casing 12 and the exterior surface of the chamber 10 by forming a groove entirely around the chamber. The object in providing this channel is to allow water to circulate around the chamber, so that the waste water will escape from the aperture 20 and have free outlet through the waste aperture or pipe 13 at whatever position the chamber is left when screwed into the casing 12.

Valve 18 is operated by water alone in the opening 22. The rod 4 operates in a slot 24, which makes the opening from the chamber 23 or opening in the valve-chamber 10 to the opening 22. The valve 11 is provided with a seat 25.

The operation may be described as follows: The valve 11 stands closed and the lever 5 is raised at the end a. To start water to running, pull on the cord 6. This will cause lever 5 to force rod 4 down and open valve 11 and raise cylinder 3. The cylinder 3 Will remain up until the water flows into box 1 and runs high enough to start in the tube or cylinder 2. Shortly after the Water begins to Iiush in the tube 2 the tube 3 will be drawn down by the force ot siphonic action or by suction exerted on cylinder 3 and close the valve ll, and thus shut off the Water-supply. The most of the water will be siphoned out of box 1 to iush a stool. What little water is left in the box and in the pipes will escape through the waste valve 18. This valve stands open when no use is being made of the Water, as the valve is only held closed by the pressure of the water. Fig. 4 illustrates a variation in the means for operating the valves. The rod is to be attached to a cap 26, having an annular fiange 27, which lits over a pipe 28. Pipe 28 is provided with a nozzle 29 and has a valve-seat 30 for a valve 31, which is attached to rod 32. The pressure of the Water in pipe 33 will keep the valve 11 closed. 'Ihe valve 18is operated as before described. When itis desirable to open valve 11, press on the cap 26. The water will then iIlow out of the nozzle 29. When the cap 26 is pressed down,4 the valve 3l is closed. In order to hold this cap down and the valve closed, a lug 34 is formed on the side of pipe 32 and a hook 35 is formed on the bottom of ange 27. A slight turn of the cap 26 Will bring the hook 35 under the lug 34 and the cap will be held down.

The device shown in Fig. 4 may be used for the box 1, or it may be used with a hydrant or sink or bath-tub or for many other purposes.

Fig. 5 illustrates a variation in the valvechamber and in the arrangement of the wastevalves. The valve-chamber 36 has a valveseat 37 for valve 38, which is the supplyvalve, and valve-seat 39 for valve 40. This valve opens and closes the waste-duct 41, and valve 38.0pens and closes the supply-duct 42. Both valves are mounted on the rod 43, which is operated in exactly the same way as the rod 4. The chamberl 36 has an offset 44, which is threaded, so that it can be screwed into such a casing as casing 12. It is claimed that the form of chamber and the arrangement ot' valves shown in Fig. 5 are the same in principle as the corresponding parts shown in Fig. 2, with the exception that valve 40 is operated by the rod instead of water-pressure.

Fig. 6 illustrates another variation of the valves and valve-chamber shown in Fig. 2. The valve-chamber is provided with a waste-duct 46 and a supply-duct 47 and a Waste-valve 48 and seat therefor 49 and a supply-valve 50 and seat therefor 51, both valves being mounted on rod 53, valve 48 being mounted on this rod by means of an arm 54. The chamber 45 is screwed into a casing at 56. The casing 55 has a Waste-pipe con'- nection 57 and a supply-pipe connection 58.

It will be understood that in the forms shown in Figs. 5 and 6 the supply-valves are closed when the rod is raised and open when the rod is drawn down in exactly the same manner as the valve shown in Fig. 2, and that the waste-valves are open when the rods are raised and closed when the rods are drawn down without changing the operation. Other changes may be made without departing from my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a closet-cistern provided with a siphon consisting of an inner and an outer limb, a pipe for supplying water, a supply and a waste valve, and a rod running through said pipe into said cistern; a lever for operating said rod and the outer cylinder of said siphon, said lever being fulcrurned on said cistern and attached at one end to one part of said siphon and having a loop below the fulcrum thereof, said rod being attached to said loop, said loop havinga number of apertures whereby said rod may be attached at various adjustments.

2. A closet-cistern having a si phon consisting of an inner and an outer limb for removing water therefrom, a pipe for supplying water to said cistern, a valve for opening and closing said pipe, a rod for operating said valve, a lever for operating said rod and the outside cylinder of said siphon and to be operated by said siphon, and a waste-valve for draining said pipe, said valve being closed by the pressure of water while Water is being supplied to said cistern.

3. A supply and a waste valvefor closetcisterns and for other purposes, a chamber for said valves, a detachable casing for said chamber and valves, said casing having an annular interior shoulder and said chamber being screwed into said casing and having an annularexterior shoulder engaging the shoulder of said casing,and a rod for operating said valves passing through said chamber, said chamber and said casing being provided with suitable ducts for said supply and waste valves.

In testimony whereof Iset my hand in the presence of two witnesses this 25th day of October, 1898.
